Ok, so i went to the software update page and downloaded the manual from there and it is different from the one included in the packaging. As said below, updates are available from: http://vortexgear.tw/vortex3.asp

Even though I did update the firmware the placement was still Irregular. The best solution that I was able to come up with is as to use a function layer on the keyboard and map the "?" Key to the "right ctl".

still not ideal, but a lot of things needs to be learnt when typing on this keyboard anyway.

Right control doesn't get used much for me so hitting it to get "?" means pressing my right palm down on the corner of the keyboard.
